just get him directions to the local rest stop... he can go there and suck off truckers...
he'll earn more money
he'll have the opportunity to learn and perfect a marketable skill
he'll have less chance of getting arrested
he'll have less chance of getting shot
he'll have less chance of getting robbed
he'll have less chance of his car being stolen
he'll have less chance of his car being impounded
he'll have only a slightly higher chance of getting an STD

and sucking truck drivers dicks is actually less gay than looking for and participating in "organized" street racing
